I wish non visa exempt countries should have at least a little bit of privilege on applications, just the fact we can travel "easier" to visit our spouses.

The only thing that makes me happy is that my husband is coming in a 23 days and after his 2 month stay here we will just wait until I get my COPR to see him again so our motto right now is "One last trip to finally be together."
Anyhow, I wanted to ask you guys, whenever you sent additional documents in which part do you add the UCI# and file #? Is it outside on the envelope or in an additional piece of paper inside? I'm planning to send my medical exams right away after I get them done on Saturday.
